The Protective Services Police Department hasn't properly trained and equipped its officers, who often haven't been sufficiently vetted and sometimes go unpunished for breaking rules, according to the IG's report.

But the Department of Real Estate Services, which oversees the Protective Services Police Department (PSPD), said many of the problems laid out in the IG's investigation "have already been resolved." The yearlong IG investigation finished last June but the report wasn't made public until last month.
